CHAIN-PUMP.

Specification of Letters Patent No. 29,466, dated August '7, 1860.

To all whom t 'may concern:

Be it known that I, Amos CoA'rEs, of Marlboro, in the county of Starkand State of Ohio, have invented a certain new and useful Improvement inChain-Pumps; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, which form a part of this specification, inwhich- Figure l, represents a perspective view of the pump box, and Fig.2, represents a section of the box and well on line A B, Fig. 1, withthe cover or top A, of the pump box removed.

In the drawings A, represents the top or cover of the box which rests onthe bottom or base B.

Near the top of the base B, is arranged a shaft a, upon which is rigidlysecured a ratchet wheel b, and main pump wheel C, the latter beingprovided with arms D, each of which has two projections c, c, at thetop, as fully shown in Fig. 3, and between which runs the chain orrubber band E.

Upon the chain or rubber band E, are attached the water buckets F,-thebuckets or water-lifters F, being made in a peculiar manner as shown inthe drawings. To the long side of the buckets or water-lifters areattached pieces CZ, which in turn are hinged to pieces c.

The buckets or water-lifters are attached to the rubber band E, byrivets passing through the pieces e, band E, and liftino' cleats f, onthe under side of the band. T he buckets or water-lifters are attachedto thel rubber band so that the cleats f, will come against every otherarm D, whereby all slipping of the buckets is obviated, while at thesame time the weight of the water in the buckets is well back of thehinge g, thus keeping each bucket from falling forward, until the point71, has advanced past the center of the wheel, the water being preventedfrom running out by the projecting part L, guntil the hinge g, haspassed by the center of the wheel, when the buckets F, suddenly fallforward and empty the water into the spout G.

The mode of hinging the buckets, in connection with cutting of onecorner of the end L, and making the backs wider than the fronts, asshown in Fig. 4, (which is a cross section of one of the buckets,) so asto give the buckets the form of a wedge at one end, and also a taperingform from back to fr"ont, constitute great practical advantages, in thisclass of pumps, since the tapering of the buckets, from back to front,enables them to force the water off laterally as they pass through thesame, similar to the sides of a boat, while the`water is retained in thebuckets until they have passed well by the center of the wheel, thusinsuring all of the water going into the spout G, while in passing downinto the water, there is less agitation caused by the buckets inentering the water, while the air in the buckets is allowed to escapemore gradually, and consequently there is much less agitation from thiscause, the air in the buckets being prevented from escaping from thesame, until they have passed by the center of the bottom of the well,and then allowed to rise up against the projecting part h, while thebottom of the bucket is being filled with water.

It-will thus be seen that my pump can be used in wells so as to bring upthe water fresh and cool from the bottom, and that too, without causingso much agitation of the dirt at the bottom of the well, as to renderthe water impure and dirty. Again the long ends L, of the buckets orwater-lifters serve the further purpose of Ventilating the well, since aconsiderable quantity of air is really raised from the bottom of thewell by the long scoop ends h., of the buckets.

In warm weather the buckets or waterlifters F, can be let down into thewell, so as to keep the water in them cool, and there held by a dog 2',which works into the ratchet wheel The dog i, can be worked by the piecej, on the outside of the box B, since the dog vf, and hand piece j, arefastened to the same journal.

The shaft a, is operated by crank H, upon its end, as shown in thedrawing. The chain E, can pass around a guide roll in the bottom of thewell, when desired. The buckets can be made of zinc or any othersuitable material.

Having described my improved chain pump, what I claim as new, and desireto secure by Letters Patent, is-

The combination with the rubber band E,

In Witness whereof I have hereunto signed my name.

AMOS COATES.
